Theory of Machine The acceleration of a particle at any instant has two components i.e. radial component and tangential component. These two components will be Opposite to each other Parallel to each other Inclined at 45° Perpendicular to each other Opposite to each other Parallel to each other Inclined at 45° Perpendicular to each other ANSWER DOWNLOAD EXAMIANS APP
Theory of Machine Angle of action of cam is defined as the angle Through which the cam rotates during the period in which the follower remains in the highest position Of rotation of the cam for a definite displacement of the follower Moved by the cam from the instant the follower begins to rise, till it reaches its highest position Moved by the cam from beginning of ascent to the termination of descent Through which the cam rotates during the period in which the follower remains in the highest position Of rotation of the cam for a definite displacement of the follower Moved by the cam from the instant the follower begins to rise, till it reaches its highest position Moved by the cam from beginning of ascent to the termination of descent ANSWER DOWNLOAD EXAMIANS APP
